| Research Abstract |
We have improved a reconstruction algorithm based on CSI (Contrast Source Inversion) method to the one that using multifrequency scattering data, and shown that the convergence of algorithm becomes fast by weighting low-frequency scattering data. Also, we have intended to stabilize the algorithm and get high-resolutive reconstructed images by applying TV (Total Variation) regularization to the algorithm. In addition, we have gotten microwave scattering characteristics through experiments in which some circular cylinders made of mortar were radiated by some electromagnetic waves. We have also investigated about electromagnetic shielding and noise reduction.
